For nations that use feet as a unit of measurement, someone with normal vision is said to have 20/20 vision.In the metric world, the measurement of 6/6 is used.
In order to be considered legally blind, someone must have vision of 20/200 (6/60) in his or her best eye with correction, and/or have a visual field that is limited to 20 degrees or less, in contrast with the 180 degree visual field enjoyed by people with healthy eyes.If the second number is smaller, it means that someone has visual acuity that is better than normal, because he or she can stand further away from an object and still see it clearly, while if the second number is larger, it means that visual acuity is worse, because the person needs to stand closer to an object to see it.In the case of someone with 20/200 (6/60) vision, he or she needs to stand within 20 feet (6 meters) to see an object which someone with normal visual acuity can see from 200 feet (60 meters) away.Good vision is a precious gift — and one that's easy to take for granted.Imagine for a minute what life would be like if your vision was permanently impaired and could not be corrected with eyeglasses, contact lenses or vision surgery.
This is the situation many people find themselves in every day, suffering from what's called "low vision."Other terms often used to describe people with low vision are "partially sighted," "visually impaired" and "legally blind."Causes of low vision include hereditary conditions, eye injuries and eye diseases such as glaucoma and macular degeneration.
